#  Spin up the given SCSI disk(s).
#
#  SCSI disks (or disks that understand SCSI commands)
#  are assumed. The immediate bit is set so the command
#  should return immediately. The disk however will take
#  10 seconds or more to spin up.
#
#  This script assumes the sg3_utils package is installed.
